[Knowledge] 8 hormones determine human sexual activity and orgasm!

Preface

• Why do people have sexual urges?
• Why do people blush during sex?
• Why do people feel so much pleasure when they reach orgasm?

Believe me, if you can fully understand the mechanism of various 'hormones' influencing sexual experience and response during the whole process of sexual activity.

Your sexual knowledge will be upgraded to a higher level, and you will have a better understanding of sex as an activity, thus laying the foundation for a harmonious and satisfying sex life.

The Effects of 8 Hormones on Sexual Activity and Orgasm

Hormones play an important role in regulating sexual activity and orgasm throughout the human sexual response cycle (arousal/plateau/climax/absence).

For example, androgens are sex drive boosters, estrogen is an important factor in maintaining sexual sensitivity, and oxytocin increases intimacy and pleasure ......

Below I will give you a detailed list of 8 hormones that have an impact on sexual activity and orgasm.

Androgens (Testosterone)

Androgens regulate libido and erectile function through actions localized in the central nervous system and the corpus cavernosum, and are physiologically very important for the production and maintenance of libido and erection in men.

The production of libido and spontaneous penile erection depends on the physiological action of androgens.

If the level of androgen is too low, it may cause a lack of libido or poor erection hardness, which seriously affects the quality of sexual life.

In addition, women's ovaries and adrenal glands also secrete androgens, which also affect their libido, but the effect is not as pronounced as that of men and varies greatly from one individual to another.

Estrogen

Estrogen plays an important role in sexual life.

It promotes the thickening of the mucous membrane of the YIN tract and glycogen production, thus helping to maintain the lubricity and elasticity of the private parts.

It maintains the blood flow and nerve distribution in the female external genitalia, which helps to increase the sensitivity to sexual stimulation, thus allowing women to experience sexual pleasure.

It also synergizes with androgens, which together affect a woman's libido.

If estrogen is too low, it will not only cause dryness in the private parts, bringing discomfort to sexual life, but also reduce the sensitivity of the private parts, thus affecting the sexual experience.

Dopamine

Dopamine is an important neurotransmitter primarily associated with reward, pleasure, and motivation, and influences sexual behavior during sexual activity in several ways.

Sexual desire: Dopamine is the core substance that drives sexual desire and enhances the desire and pursuit of sexual stimulation by activating the reward system in the brain (nucleus ambiguus, ventral tegmental area, etc.).

When people are sexually stimulated, dopamine release increases, which enhances interest and initiative in sexual behavior.

Maintaining sexual arousal: Dopamine and other hormones synergize with each other to enhance the experience of sexual stimulation and prolong sexual arousal by affecting blood flow to the sensitive areas of the private parts, making them more sensitive.

Enhanced orgasmic experience: dopamine peaks during orgasm, which can lead to intense feelings of pleasure.

And, by activating the brain's reward circuit, it forms a positive memory of the sexual act, making people increasingly enjoy and enjoy orgasms.

Oxytocin

Oxytocin is a neuropeptide hormone synthesized by the hypothalamus and released by the posterior pituitary gland.

Although it is more common in labor and lactation, its function in sexual activity should not be underestimated as well.

In particular, it plays a unique role in promoting intimacy, increasing emotional trust in partners, and reducing anxiety about sexual activity.

Additionally, when orgasm is reached, oxytocin triggers uterine and pelvic floor muscle contractions, which increases the pleasure of orgasm (more pronounced in women).

If oxytocin is not secreted sufficiently, it may trigger frigid talk, orgasmic difficulties or sensual detachment, which are not conducive to sexual harmony.

Serotonin (5-hydroxytryptamine)

Often considered an inhibitory hormone, serotonin is most closely related to male sperm control and has been confirmed by animal experiments and human model studies.

An increase in the concentration of 5-hydroxytryptamine (5-HT) between neurons facilitates delayed ejaculation in males; a decrease in the concentration or a decrease in the sensitivity of the receptor may lead to premature ejaculation.

In the same way, serotonin inhibits female libido, reduces neural sensitivity in sensitive areas, inhibits the buildup of sexual arousal, and delays the onset of orgasm.

However, serotonin can work synergistically with other hormones to regulate sexual satisfaction. This “inhibition and balance” of the two-way complexity of the role of the joint impact of people's sexual activity.

Endorphins

Endorphin is a naturally occurring neuropeptide, mainly through the combination of opioid receptors to play an analgesic and pleasurable effect, known as a natural painkiller.

In the process of sexual activity, the role of endorphins throughout the human sexual response cycle.

They can inhibit the release of cortisol (stress hormone), relieve tension and create a relaxing sexual atmosphere; they can also help people reduce pain and discomfort and have a good sexual experience; and they can work together with other hormones to trigger deep relaxation and fulfillment, resulting in the emotional connection of “warmth afterward”.

Insufficient endorphins can lead to a lack of sexual pleasure or loss of libido. If there is an over-reliance on sexually stimulated endorphin release, the balance of the natural opioid system may be disturbed, leading to sexual addiction.

Norepinephrine

Norepinephrine is a catecholamine neurotransmitter that is released by sympathetically regulated brain-related regions and is primarily involved in stress response, alertness, attention regulation, and cardiovascular function.

During sexual activity, norepinephrine has a dual role, either enhancing physiological arousal to promote sexual excitement or causing anxiety or sexual dysfunction due to over-activation.

If norepinephrine is too low, it may lead to low libido and difficulty in maintaining erection; if norepinephrine is too high, it may lead to premature ejaculation, sexual anxiety, and orgasmic disorder.

Epinephrine

Epinephrine is a hormone secreted by the adrenal medulla and an important neurotransmitter regulated by the sympathetic nervous system, and norepinephrine belongs to the same catecholamines.

During sexual activity, adrenaline elevates people's heart rate, blood pressure and blood glucose levels by activating beta receptors, which not only provides energy reserves for sexual activity, but also enhances sensitivity to sexual stimulation, helping to create an erection or engorgement of the YIN tract.

If adrenaline levels are too high, it may activate its “fight or flight” mode and inhibit the parasympathetic-dominated sexual relaxation response, leading to erectile dysfunction, vaginal dryness, or loss of libido.

Conclusion

It can be seen that although sexual activity and orgasmic experience are directly dependent on sexual stimulation, the essence behind it is actually regulated by the brain.

It can be said that the brain is the largest sex organ of human beings, and is the “commander-in-chief” of sexual activities and experiences, from the primitive impulses to complex emotional connections are regulated by it, involving the synergistic effect of multiple brain regions, neurotransmitters, hormones and external stimuli.
